摘要: 工業互聯網現場存在大量異構設備和網絡帶來的復雜性以及工業生產的實時性和可靠性問題,如果數據分析和控制邏輯全部在云端實現,難以滿足工業場景的網絡需求,而通過邊緣計算在服務實時性和可靠性方面能夠滿足工業互聯網的發展需求。提出了面向工業互聯網的OLT融合邊緣計算三種技術方案,主要通過邊緣計算和OLT的業務連接、路由轉發以及管理功能等方面進行了分析。對比了具有增值功能的OLT內置型邊緣計算、具有通用功能的OLT內置型邊緣計算以及OLT外置型邊緣計算三種方案的差異性,根據其差異性提出了適用于不同工廠的場景需求。

Abstract: The industrial internet site has the complexity brought by a large number of heterogeneous devices and networks, as well as the real-time and reliability problems of industrial production. If data analysis and control logic are all implemented in the cloud, it is difficult to meet the network requirements of industrial scenarios. However, edge computing can meet the development needs of the industrial internet in terms of service real-time and reliability. This paper proposes three technical solutions for optical line terminal(OLT) converged edge computing for industrial internet,mainly through the edge computing and OLT business connection, route forwarding and management functions and other aspects of the analysis. Comparing the differences among the three solutions of OLT built-in edge computing with value-added functions, OLT built-in edge computing with general functions, and OLT external edge computing, according to their differences, the scene requirements applicable to different factories are proposed.
Key words : edge computing;optical line termina;built-in resource board
